I'm trying to improve the performance of a page loading of an app where I use <telerik:RadTreeView. The tree is two levels down with it's own <telerik:HierarchicalDataTemplate . I used IsVirtualizing which gave a little more performance boost, but not much because the number of items that is listed in the tree view is still high enough to impact the performance.
If it was listing only like 5 items, it would have satisfied me. The user can then scroll the tree view, and see the remaining items. But initially itself when the items are displayed, the number of items shown are 20 or above. How can I control how many items should be shown? I tried to set the tree view height but that did not help. I tried also to set the height of the grid row. That did not help.
Any help is appreciated.
